Mapping the PFAS Contamination Crisis: New Data Show 610 Sites in 43 States

The known extent of contamination of American communities with the toxic fluorinated compounds known as PFAS continues to grow at an alarming rate, with no end in sight. As of March 2019, at least 610 locations in 43 states are known to be contaminated, including drinking water systems serving an estimated 19 million people.

The latest update of an interactive map by EWG and the Social Science Environmental Health Research Institute, at Northeastern University, documents publicly known pollution from PFAS chemicals nationwide, including public water systems, military bases, military and civilian airports, industrial plants, dumps and firefighter training sites. The map is the most comprehensive resource available to track PFAS pollution in the U.S.
